LDP SURETIES AND FEE REQUIREMENTS

LDP SURETIES AND FEE REQUIREMENTS

Performance Right of Way Improvements Surety Prior to the final approval of the Land Disturbance Permit by the City of Johns Creek Community Development Department, a surety is required for the proposed right of way infrastructure improvements. The surety will be released upon installation and City approval of all improvements. Surety calculation forms and templates are available on the city’s website. Development Regulations Section 113-71 Clear-Cutting/Tree Replacement Surety If a potential development site proposes to clear cut all or the majority of the property, and saved existing trees cannot meet the required tree density for the site, or are less than the trees required to be planted, a surety may be required. The surety is a mechanism for the City to cover any potential cost associated with tree replacement on the site in the event of property abandonment. The required surety amount will be 125 percent (%) of the total cost for replanting trees to satisfy the tree density for the site. The owner can obtain a replacement cost from a plant nursery or base the surety on $250.00 per two (2) inch caliper tree. The surety can be in the form of an Insurance Bond (A-6 or better bond rating), Cashier’s Check, or Letter of Credit and must be submitted prior to the issuance of a land disturbance permit. Surety calculation forms and templates are available upon request. City Code, Tree Preservation Ordinance Section 109-201 Erosion Control/Stabilization Surety Every permit applicant shall be required to post a cash surety, irrevocable letter of credit, or insurance bond of $3,000 per disturbed acre prior to the issuance of a land disturbance permit. The surety is a mechanism for the City to cover any potential costs associated with stabilization and compliance of all disturbed areas and stormwater infrastructure including, but not limited to, permanent grassing, desilting detention ponds, water bodies, stormwater facilities, roadways, reestablishing damaged buffers and similar or related items. This surety will be released upon approval of final stabilization from the Department of Community Development. Surety calculation forms and templates are available up the web page. City Code, Soil Erosion & Sedimentation Control Ordinance Section 109-152 Local Issuing Authority Land Disturbance Fee Every permit applicant proposing to disturb over one (1) acre shall be required to pay a $40 per disturbed acre fee prior to the issuance of a land disturbance permit. This fee, in addition to other city permitting fees, is to be paid by the primary permittee as defined in the National Pollutant Discharge Elimination System State General Permit. A copy of the NOI, check to EPD and return receipt are required to be submitted to the City prior to issuing permit. City Code, Soil Erosion & Sedimentation Control Ordinance Section 109-152
